sales return from unregistered dealers how to file in GSTR 1

YES , I FACED THE SAME PROBLEM WHILE FILING GSTR 1 

AND I CALL HELPDESK TO ASK HOW TO SHOW THE SAME  ... THEY HAVE NO IDEA OTHER THAN U ALWAYS ASKED FOR SCREEN SHOTS 

WHAT HAVE I DONE ??
I DELETED THE RESPECTIVE UNREGISTERED SALES AS THERE IS NO SUCH OPTION TO ADD CREDIT NOTE FOR THE SALES RETURN FROM UNREGISTERED 

but I do that sales in July and issue credit note in nov

We can enter the details of sales net of debit note and credit note in tile 7 ie B2C others, as we do not mention the invoice details of B2CS invoices, there is no need the mention the credit note issued against the sales return. So we could deduct the sales retuns from the sales and enter the net figure in this tile.

if sales return is more than sales of the month, negative sales may not be accepted by the system

whether sales returns of unregistered dealers are eligible for ITC i.e., we can reduce the output to the extent of sales returns of unregistered dealers
